Tire Pressure Monitoring System problems of the 2009 Mercedes Benz C300

Tire air leaking result from rim crack within 1st year of ownership of 2009 mercedes C300. It is original manufacturing defect, and the manufacture respond very slow for our report of problem.

Tire pressure monitor keeps coming on. I have taken the car to 2 different retailers and they just reset the tpm. They cannot find any issues with the tires or the tpm. This means that the tpm software is defective. One of them said to just look at the tires to check if there is enough pressure and keep driving. I called the benz customer service department and they just referred me back to the retailers.
